The input delay is controlled by STIN[n]BD2-0 (bits 8 - 6) to control the bit shift and STIN[n]SMP1 - 0 (bits 5 - 4) to
control the sampling point in the Stream Input Control Register 0 - 31 (SICR0 - 31).
STi[n]
The first 3 bits represent STIN[n]BD2 - 0 for setting the bit delay
The second set of 2 bits represent STIN[n]SMP1 - 0 for setting the sampling point offset
Note: Italic settings can be used in 16 Mbps mode (1/2 and 4/4 sampling point)
Example: With a setting of 011 10 the offset will be 3 bits at a 1/2 sampling point
